CONDENSER.

condenser which is simple in construction` and efficient in operation.One ofthe more specific objects of the invention is to provide a jetcondenser of the high vacuum -f type in which the injection water isuniformly distributed in the condenser zone to produce rapid and eectivecondensation of the steam. Another object is to provide an eflicient jetcondenser of large capacity in which the injection water is effectivelydelivered into and distributed in the condensing Zone by gravity. i Afurther object is to provide means for effectively injecting coolingwater into all portions of the condensing zone of relatively large jetcondensers. A further object is to provide a high vacuum jet condenserwhich will retain maximum efficiency throughout a considerable range ofoperating conditions.

A clear conception of an embodiment of the invention may be had byreferring to the drawing accompanying and forming a part of thisspecification in which like reference characters designate the same orsimilar parts in the various views. y

Figure 1 is a fragmentary transverse vertical section through a jetcondenser having the invention applied thereto.

Fig. 2 is a top view of the inner casing which forms the condensing Zoneof the condenser.

The condenser comprises essentially a vertical cylindrical outer casing6 having a steam inlet 1 at the upper end thereof7 a water inlet 2 atthe side thereof near the top of the outer casing, an air outlet 3somewhat below the water inlet 2, and a water outlet, not shown, `nearthe lower end of the casing. Whilethe casing 6 is disclosed ascomprising several detachable sections, this construction is notessential. The inner casing Specification of Letters Patent.

5 comprises a perforated annular upper wall forming a condensing zoneand having a downwardly extending constricted portion forming an outleti leading from the condensing zone. The mid portion of' the casing 5 isprovided with an outwardly eX- tending flange which is secured to anannular wall 15 the lower extremity of which engages an upper surface ofthe casing 6 and provides a support for the inner casing The annularwall 15 besides forming a support for the casing 5, for-ms a waterdistributing pocket surrounding the lower portion of the perforatedupper end of the casing 5.

The annular upper wall of the casing 5 is provided with several circularseries of perforations or orifices 12, 13, 1li, arranged one above theother and opening directly into the condensing zone. rfhe orifices 12 ofthe upper series open into inwardly eX- tending troughs l2, which aresecured to the casing 5 and have their inner ends opening toward thecenter of the condenser. The orifices l2 of the upper series may be madelarger' and fewer in number than those of the intermediate series 13,while the orifices 13 of the intermediate series may be made larger andfewerin number than the orifices 14 of the lowermost series. Theorifices of the adjacent series are preferably arranged out of verticalalinement with each other, thus giving them a staggered relation to eachother. The upper extremity of' the perforated annular wall 5 is providedwith a series of inwardly extending open troughs 11, which in thepresent disclosure are arranged substantially radially. Each of thetroughs 11, 112, is provided with perforations or orifices 18, 19,respectively, opening directly into the condensing zone. The troughs 11of the upper series are preferably arranged out of vertical alinementwith the troughs 42 of the lower series. The orifices 12, 13, 14;, andtroughs 11 are preferably made of such size and number that each serieswill tend to deliver substantially the same amount of cooling water tothe condensing zone that an adjacent series delivers.

The central portions of the condensing zone is provided with a verticalcasing 9 having superposed series of orifices 2O opening directly intothe condensing zone. The

openings 2O are so arranged that they will I inject water into thecondensing zone away from the center thereof. The openings 20 ofsuccessive series are preferably arranged out of vertical alinement,thus giving them a staggered relation to each other. The casing 9 issupported from the wall 15 and casing 5 by means of pipes 8 which alsoserve to admit injection water to the interior of the casing 9 from thewater inlet 2.

The steam inlet 1 of the casing 6 is arranged in linewith the upperportion of the casing 5 and also serves as an inlet to the condensingZone. `The water inlet 2 con` nects with an annular passage 22 whichsurrounds the annular wall l5. The annular bafile wall 16 extendsdownwardly from the cover of the casing 6 and forms an annular airpocket 23 at the extreme upper end of the condenser. The constrictedlower portion of the casing 5 which forms the outlet 4, projectsdownwardly into the collection chamber at the bottom of the casing 6 toa point adjacent the air inlet 3. The casing 6 andconstricted outletportion of the casing 5 coact to form an annular air pocket 10 fornon-condensable vapors, which communicates directly with the air outlet3. The lower central portion of the outlet 4 is provided with a hood 7supported from the lower constricted portion of the casing 5, theinterior of which connects directly with the pocket 10 through the pipe21. The air pocket 10 is connected with the air pocket 23 at the upperend of the condenser bymeans of a series of pipes 17.

During the normal operation of the device, the exhaust steam flowing athigh velocity is admitted to the condensing zone within the casing 5through the steam inlet 1. The injection water admittedl through thewater inlet 2 fiows around the annular distributing passage 22 and intothe space directly adjacent the perforated wall of the casing 5. As theinjection water flows through the orifices 12, 13, 14, and the troughs11, 42, it is delivered by gravity into.-

the condensing Zone and toward the center thereof in the form ofstreams.

Some of the water entering the troughs 1l, 42, is precipitatedlongitudinally into the condensing zone through the orifices 18, 19,while the remainder of the water pass ing through these troughs isdelivered over the inner ends thereof to points near the center of the.condensing zone. A portion of the water admitted into the distributingpassage 22 passes through the pipes 8 into the interior of the casing 9,fromwhich it is delivered through the orifices 20 in the form of streamsdirected away from the centerof. the condensing zone. As the steamadmitted through `the inlet 1 passes Y rangement of the troughs 11, 42,and the orifices 12, 13, 14, 20, to take acircuitous path between thestreams flowing from these orifices and troughs. Due to the great numberand the staggered relation of the streams of water admitted to thecondensing zone, the steam is quickly condensed and the mixture of waterand non-condensable vapors is delivered to the chamber at the loWer endof the casing 6, through the outlet 4. The mixture of water andnon-condensable vapor thus delivered to the lower portion of the casing6 is discharged from this casing in the usual manner. Some of thenon-con densable vapors escaping fromv the mixture rise into the hood 7and pocket 10, from which they are withdrawn through the air outlet 3.

The provision of the walls 15, 16, insures perfect distribution of theinjection water to all portions of the condensing zoneand prevents localinjectionof a greater portion of the water to one side of the condensingzone. The air pipes 17 and the pipe 21 permit ready withdrawal by theair pump of any 'vapors which may gather in the pocket 23 and the hood7. The portion of the casing 5 which forms the outlet 4 is preferably soformed that the streams of water delivered through the lower orifices14, substantially follow the contour of this portion of the casing; Onaccount of the difference in head of the water delivered to the troughs11, 42, and the orifices 13, 14. respectively, it will be noted thatthestreams delivered through the lower orifices 14 `will tend to passinwardly to a greater extent than those delivered from the upperorifices. In order to prevent excessive-inward travel of thelowermoststreams, the lower-portion of the perforated wall ofthe easing5 is formed downwardly diverging.

In order to prevent they formati-on of a dead space in cond'ensersof`lrelatively large size in which non-condensable vapors might collect andinto which no injection water is projected, the centra-l perforatedcasing 9 is provided. llhilfe the 'troughs 11, 42", tend' to eliminatethe formation of' such dead space, the casing 9 and orifices 20 willpositively prevent its formation. of water delivered fromthe orifices18, 19; 20, coperate with' the streams delivered from the ends of thetroughsL and fromy the lower orifices 13, 14, and produce a maximumamount of coo-ling water surface.

It is desirable inthe operation ofthe condenser to have the` injectionwater iiow through the orifices andtroug-hs under the impellinginfluence vof gravity and hydro*- static head' only, and' with thecondenser operating at full load to have'4 substantially the sameyquantity of coolingwater entering thel condensingzone through eachseriesof orifices inthe casing 5. TheseV results'are' at@ The streamsk raschertained by the use of the present invention. While the troughs 1l, 42,have been disclosed as formed integral with the casing 5, suchconstruction is not essential.

It 4should be understood that it is not desired to be limited to theexact details of construction shown and described, for obviousmodifications will occur to a person skilled in the art.

It is claimed and desired to secure by Letters Patent,-
